Sharpie Pencil Features Liquid Erasable Ink

Pencils as we’ve known have always come in the form of solid graphite sandwiched in the middle of a piece of wood. However, a new writing instrument with a special liquid erasable ink from by Sharpie is set to change all this.

The new pencil/pen hybrid has a plastic casing unlike traditional pencils and is filled with a special liquid graphite solution that is erasable for the first three days. After three days, as the writing is exposed to air the ink becomes permanent.

While it does seem quite revolutionary, I doubt it can actually become a substitute for actual pens and be used for legal stuff like making contracts. Especially so for the initial three days, as the writing from the liquid graphite can be made to disappear like novelty invisible ink.
